I think the mid 80s cruiser rotors are what I used. I can't remember which ones I used but I seem to remember using them from whatever Cruiser was in the mid to late 80s. I just bought them from a local parts store which was the cheapest way to get them at the time. Don't count on them being in stock however. I'm sure somebody will chime in to give you a definitive answer or otherwise you may have to search. I know it is on the site somewhere.
